WIVLLIAH CAMPBELL raisons, or' MANSFIELD, LOUISIANA TRAILER ATTCHMET FOR VEHICLES.

My invention relates to improvements in v: trailer attachments for vehicles, whichconsists in combinations, constructions and arrangements herein described .and claimed.

5 An objectof the invention is thefpro- -vision of simple, reliable and eiiicient means lfor attaching the reach pole' of a.'l

trailer to the rear bolster. of the leading truck, so that the reach pole of the trailerv lfl can swing both vertically anddiorizontally relatively to the part of the leading vehicle with which it is attached.' i

A further object of the invention is the provision of an attachment of the character 'f'.describedwhich atfordsffacilities for. en-

gaging .with the 'load supporting member or bunk that is disposed at the (rear of the leading' vehicle for co-o erating with the trailer to support a loa the load supporting member at the rear .of

the leading vehicle will swing horizontally' as a unit about the same verticalaxisand therefore the load lthat is partly supported i5 on the trailer and partlyv on theload sup- 4porting member at therear of4 the leading s vehicle will be securelysupported in a uniform manner irrespective of .the angular relation of`v the' longitudinal axis of the 0 reach /pole to the'longitudinal axisyof the leading l, vehicle as well as when the trailer 4- is'moving directly in line with the leading Figurefl! is 1a, vllrspective View., showing 5 the impovedtr'ai er attachment applied to therearendofa vehicle,` ``fFigure 2 is, a# fragmentary Y vlongitudinal 4 section'through the rearbolster and the transversebunl of the leading vehicle; as well as the part-s of the attachment which are' disposed betweenthe rear. bolster and bunk of the leading vehicle,

The inventionprovides *a reach pole which is'oli'set upwardly for part of its length adjacent to the forward end thereof as indicated at 5. The reach` pole iswonly l partly illustrated in the drawings,ithe rear end portion thereof being omitted as well as any illustration of a trailer truck, since it will be understood from the description that will follow that the rear'vend portion of the reach pole may have any suitable known structure and may be attached to a trailertruck in any suitable known manner. The bodvj of the reach pole is tubular in form.- The reach pole also includesy anv attaching section 6 at the. forward end thereof'which comprises a tubular portion 7 .adapted to litin the forward end portion of the upwardly offset part 5 of the reach pole bod7 and to be rigidlysecured to the body of the reach pole byl fastening devices such as the bolts 8 which are projected through alinedv openings in the lapped portions Lof the oiset/ portion 5 offthe body of the. reach pole, and the attaching section 6 of 'the reach pole. A head 7 of thef attaching section 6 `of` the reach pole is merged at its forward end into a pair of spaced ears @which are offset laterally in opposite directions from the axial line ot'.

theportion 7 of the attaching section 6 of the reach pole. The ears 9 curve forwardly and downwardly and are aperturedfadjacent to their extremitiesby alined transverse openings 9. These openings 9 there- Afore are located below the axial line of the portion 7 of the attaching section 6"of the reach pole,

A substantially 'flat bearing plate y1() isl superimposed onthe middle portion of the bolster 2 of the vehicle 1 and preferably has a 'width equal to that of the underlying lportions o f the bolster 2. This bearing 'plate 10 may be held against movement onthe bolster 2 bythe screws 10 and the fas- INI y edges of this extension 12 bein tening devices indicated at ".y The plate 10 also has a pendent boss 21 which fits snugly between longitudinal sections of the bolster 2 and aids in staying the plate l0 to the bolster 2.

An attaching plate 11 is of' less Width than the bearing plate 10 for a greater part of its length and has a smooth plane lower face adapted to rest latvvise on the bearing plate 10. The attaching plate 11is extended laterally intermediate its ends as in.- dicated at 12 for part of its length, the side beveled vas best seen in Figure 5, so that tie extension decreases in' width toward its outer end. The body of the attaching plate 11 also is formed with pairs of transversely alined upwardly and outwardly extending lugs 13 at y. the opposite ends of the attaching plate for purposes to be presently described. The body 'of the attaching plate 11 also is formed with a lateral extension 14 intermediate the ends of thewbody of the attaching plate and opposite the lateral extension 12. The extensionv 14 is enlarged upwardly. at

its opposite ends to provide a' pair of up-v standing ears 15 whi h have aligned horizontal openings 16 ormed therein. The end portions of the body of the attaching plate 11 also are vformed with upstanding osses 19 which are located intermediate i vthe side'edves ofthe body of the attaching tically relatively to the bolster 2;-

' larged at their vlower ends.

The attaching plate 11 then i-s superimposed on the'bearing plate 10 with the extension 12 at the forward side of the attaching Cplate and with an' opening 22 that is forme in the plate 11 in alinement with the opening 20. It is obvious that the attaching pate 11 will be-connected with the bolster 2 to swing about a vertical axis when a vertical pivot pin 23 is disposed in the alined enings 22`and 20, as best seen in Fig. 3. ith this arrangement, the extension 14 will' be'disposed at the rearward side of the attachin plate. The forward end of the reach pol .betweenl the ears 15 so that the openings 9 in the horizontally spaced ears` 9 of the attaching head section of the reachpole are in alinement with the openings' 16 lin the ears 15` and a horizontal element 24 is-projecvted through the alined openings 16 and 10 in the earsl and 0. The reach-pole thus will be 'connected with the attaching plate 11 to swing about a horizontal axis and in consequence, the reach pole .is permitted to swing both horizontally an'dlver- A transverse' supporting member or bunk is indicated at 25. and is adapted to be suplugs .-13 4`are aada'ptedto straddle the lower then is disposed pivot element 23 is a boltf'of suflicient length 75 y to extend through the aligned openings 28, 22 and 20. IThe. lower en lof'this b olt 23 is engaged by a nut 23%" The end portions of the bunk. are formed with" vertical openings 25a in line with-'the/,openings 19 in the'pla'tey 11.

Therefore, swinging movementA of the `attachingplate 11 about vthe axis of the vertical pivot pm 23 vwill cause alike movement of the bunk 25 and the bunk 25 and the'y reach pole 4 there zontal1y. l

Obviously, the Vinvention is' susceptible o'f embodiment informs other than=`that which is illustrated inwthe accompanying drawings, and I therefore consider as my'ownall such modificationsand adaptations 'thereof as fairly fall within :the scope of. the appended claims.
